The Prince Has a Treasure Bag

He traveled through time and became the prince of the Tang Dynasty, Li Chengqian, and was bound to a different-dimensional pocket from Doraemon? Li Chengqian originally wanted to take out the gourmet tablecloth and An Xin be a salted fish ball loved by his parents and younger siblings. When I have nothing to do, I use the bamboo dragonfly to take my sister for a ride, and I use the memory bread to help my brother cheat. It's a happy little life. However, he has a workaholic father who always wants to use his pocket to make some big news. "Chengqian, this thing may benefit the country and the people?" As a result, air cannons blasted open the Turkic royal court, projectors illuminated the debates in the court, and fast-growing plant liquid irrigated thousands of miles of fertile land... When Li Chengqian came to his senses, he had been scorched by the gazes of civil and military officials and enthusiastically supported by all the people. Li Shimin put his arms around his shoulders and pointed to the prosperous age at his feet: "Qian'er, look, this is the country I have built for you... Wait, this seems to be the country you have built for me?" This book is also known as: "I promised to be a salted fish, but you asked me to make changes", "The No. 1 Props Master of the Tang Dynasty", "My Father Li Shimin Forced Me to Use Black Technology".
